System for the determination of glucose in fluids
First Claim
1. A test capable of the determination of the presence of glucose in a liquid test sample which device comprises a carrier matrix which bears the residue left by impregnating it with a liquid reagent solution of solvent, glucose oxidase, a peroxidatively active substance and m-anisidine with subsequent evaporation of the solvent to leave the dry reagent composition wherein the reagent components are present in the carrier matrix in amounts and proportions such that the carrier matrix is capable of differentiating between concentrations of 2,000 and 5,000 milligrams of glucose per deciliter.

Abstract
The present invention involves an improved test system for the determination of glucose in aqueous fluids of the type which comprises glucose oxidase, a peroxidatively active substance and chromogen. The improvement involves the use of m-anisidine as a chromogen which permits the semi-quantitative determination of glucose at higher concentrations than is possible with previously used chromogens.
